Planting Directions: Sow seed indoors 10 weeks before last frost date. Celery seed needs light to germinate, so barely cover the seed. Soil temperature for best germination is 70˚ and soil temperature for best growth is 60-70˚. Transplant outdoors when day temperatures are stay above 55˚ and night temperatures are above 40˚. Plant in rich soil that has been amended with a good amount of rich organic matter. Keep celery weed free and water as needed to keep soil moist but not soggy. Side dress with fish emulsion or similar product every 2-3 weeks throughout the growing season for best production and quality.
